Fault Passage Indicators For Line Networks
ComTroll®
Surveillance and Automation System The
electric utility industry is experiencing an increasing demand for a more
efficient and cost-effective operation of the distribution network.
De-regulation, increased competition, demand for better quality of supply and
penalty for non-supplied energy is becoming the everyday challenge for an
increasing number electricity distribution companies. Changes
in the industry have resulted in an increasing interest in distribution
automation and surveillance as one means of meeting the new demands for
customer satisfaction and profitability. NorTroll’s
system for distribution automation called ComTroll® is designed for
remote control, surveillance and automation of secondary rural and urban
distribution systems. ComTroll
is a modular system with different building-blocks allowing the utilities to
tailor-make a system to meet their own demands for functionality and complexity.
NORTROLL offers: Fault passage indicators. Software for remote control and surveillance of the network. Outstations for remote operation of overhead line and underground cable switchgear. IInterface for easy integration of the ComTroll system with other SCADA systems. The
ComTroll system is developed to identify the fault-location, isolate the faulty
section and restore the healthy part of the system in a minimum of time. | |||||||||||||||||||||||||||||||||||||||

Communication: The ComTroll
system is based on the modern and flexible LonWorks® technology with
the integrated LonTalk® protocol. The system is very suitable for
use in independent as wells as shared networks. LonWorks technology is extremely robust and reliable, ensuring the high level of performance demanded by the utility industry. LonWorks allows Nortroll to utilise a wide range of communication carriers such as radio, twisted pair, power-line carrier, fibre-optics and telephone/GSM LonWorks
technology is based on distributed intelligence enabling fast and
efficient communications with a minimum of traffic. Nortroll
has specialised in Radio communication (VHF/UHF) and has adapted the LonWorks
technology to be used in an independent radio infrastructure, allowing the use
of repeaters to ensure the radio coverage to remote out-stations and indicators.
The system allows for an out-station to act as a repeater for other out-stations
or fault indicators. Nortroll
has further developed the system to allow the repeaters to be structured with
Sub-net addressing to ensure a minimum of traffic and a maximum of throughput
ComTroll Independent radio infrastructure Low
power consumption allows the outstations and repeaters to be charged from a
solar-panel making it very simple and cost effective to build the radio
infrastructure. No need to think about availability and cost of bringing mains
to the different locations of the outstations and repeaters. This avoids the
necessity for considering the cost and availability of mains power at all
locations of the outstations and repeaters. Building-blocks: The NORTROLL system consists of different building-blocks, ranging from software for monitoring and remote control of the network to outstations with integrated RTU’s and fault indicators for overhead-line or underground cable. All products have been designed with the focus on high modularity and flexibility, very low current consumption, a non proprietary protocol, and an easy integration with other SCADA systems. NetTroll® and NetDraw® NetTroll is a micro SCADA system for remote
operation of switchgear, monitoring of indicators and switchgear status and
collection of other useful information for the different operation and
maintenance of the distribution network. NetTroll offers a graphical, user friendly
system, with an intuitive man machine interface. The system runs on the Windows
NT/2000/XP operating system. PC hardware requirements are: 200 MHz Pentium II
processor, 64 MB Ram a minimum of 500 MB available disk-space. NetTroll
Features: User
adaptable graphics Event
log / Alarm Log
NetDraw is a drawing editor for NetTroll and gives the user full control of the screen graphics. Symbols for outstations and indicators can be chosen from the symbol library or can be designed by the user (bit-maps). | |||||||||||||||||||||||||||||||||||||||

ComTroll 155 A/B (Compact RTU)
ComTroll 155 A/B is a compact RTU with RTU, modem, radio DC/DC charger all built in to one unit. The ComTroll 155A/B can be used for remote control of one actuator or one motorised switch. The ComTroll 155 A/B can be supplied with a cabinet for outdoor mounting. NOTE! Product will be available Q2-2003. ComTroll Repeater The ComTroll stand-alone repeater can be based on the hardware of the compact RTU or the ComTroll 2XX B/BR. The repeater can be configured with Domain and Subnet filtering, keeping the radio traffic to a minimum. Any Nortroll RTU can be configured as a combined repeater extending the radio coverage to outstations further out in the network RTU Alternatives. Nortroll Outstations can be
equipped with a variety of RTU’s. From the compact RTU offering a simple
low-cost solution for operation of one switch to the modular rack based RTU
20/25 offering a different numbers of input’s and output’s. The RTUs has a very low current consumption and can be powered from a 30W or 60W solar panel. Battery alarm and general digital inputs for
monitoring of indicators or other types of alarms from the outstation. The
RTU-25 has two analogue inputs giving the operator the possibility of monitoring
the voltage or current level at the outstation. The rack based RTU can also be

provides a variety of services to the utilities to ensure maximum performance of
the ComTroll system. Services available from Nortroll Engineering are:
radio survey, planning of the radio infrastructure, installation and
commissioning, tailoring of software and training. AutoTroll®
Feeder and Network Automation. The AutoTroll concept has been
developed to further maximise the value of the ComTroll system. Automatic
disconnection of a faulty feeder or a reconfiguration of the network without the
need for operator intervention will further reduce the outage-time and
restore power to the healthy part of the system in less than a minute. The total
time to restore power is dependent on the complexity and the number of
outstation involved in an automation scheme. Feeder Automation. Input from a LineTroll or
CableTroll fault passage indicator to a Nortroll RTU can locally initiate an
opening of a switch. The output from the indicator can be delayed to make sure
that the outstation receive the command to open the switch after the indicator
has verified that there is a permanent fault on the feeder. The outstation will
then open the switch when the line is de-energised before the delayed re-closing
appears. When the delayed re-closing appears the faulted feeder or branch will
have been disconnected and the healthy part of the feeder will be restored. Network Automation. An automated sequence can be programmed in the AutoTroll module within the NetTroll micro SCADA software. A sequence can include a number of outstations even from different feeders. Different events in the network or RTU I/O states can be set as a Trigger or an Inhibitor for an automated sequence. Triggers and inhibitors are set up in a step-table describing what should happen. When a trigger occurs the AutoTroll system will start a sequence of opening and closing switches according to the step-table for the sequence. The automatic sequence will isolate the faulty section and reconfigure the network unless an inhibitor prevent the sequence being executed. The AutoTroll feeder and network automation can be used in a stand alone Nortroll system or in systems where the Nortroll outstation are integrated into other SCADA systems.
